For properties in general, the easiest way to estimate taxes is to multiply the assessed (or anticipted reassessed) value by the net mill rate, currently 2.997%. 

Let's say the GRM (gross rent multiplier) was 100. 100x50= $5000 adjustment in the sales comparison approach.

When determining the net income, I simply multiply gross rents by an expense ratio to determine the net income.

Anyone on here use any advanced mathematics during deal analysis like determining rent increases, such as using Lagrange multipliers on a constraint curve of a function of price and vacant to maximize profit.

Now multiply that by a lot of houses and you can see even sub too foreclosure rescue to do right you need minimum 100s of thousands to millions of dollars in cash to make it work.. can U do one or so sure.. but a ton of work just to capture some equity.. in our case it was either make a business out of it and do volume or just pass on it..

The risks of investment inactivity have multiplied considerably.

Personally, I have pretty good idea of how much my professional time is worth (from having been in the corporate world for a long time) and I use that as a baseline.Ultimately, at the end of every year, I do a quick calculation that estimates the number of hours I worked in the real estate business, and multiply that by my hourly "worth", to generate my hypothetical salary that I should have expected to take from the business.I then create my financial statements (most importantly my P&L) that counts that "salary" as an expense and analyzes the success of the business as if I had paid myself that salary.

The question to ask yourself is “am I the type of person that would take the money spent on real estate education and be able to multiply it 5 or 6 times in the next year or two.” 

Generally it's normal to take the last three months of income (called "trailing 3" or "T-3"), multiply it by 4 (which annualizes it) and then subtract the expenses from the last twelve months (called "trailing 12" or "T-12"). 

Just looking briefly in areas around me (Chicagoland), monthly board for one horse can be anywhere from $300 to over $1000 - and multiply that for however many stalls that are available and it seems like you could see some serious cash.
